IMPROVEMENT IN CHEMICAL FIRE-EXTINGUISHERS.

Specification forming part of Letters Patent No. 149,044, dated March31, 1874; application filed October 25, 1873.

To all whom it may concern:

Be it known that I, JOHN A. KLEY, of the city of Chicago, in the countyof Cook and State of Illinois, have invented new and useful Improvementsin Chemical Fire Extinguishers, of which the following is a fulldescription, reference being had to the accompanying drawings, in whichFigure 1 is a vertical section. inclusive are details.

My invention consists, first, in providing a hinged bottle-holder toreceive the glass bottle containing the acid; in providing a guard tokeep the bottle-holder in an upright position while in use; in providinga lead packing for the cover, as described; and in the other devices andcombinations herein claimed.

In the drawings, A is a cylindrical reservoir, constructed, in the main,as usual, of any suitable material. a is a neck, provided with ascrew-thread to receive the cover I). 0 is a bottle-holder, hinged at kto the part d, which is provided with a lead band, a, beveled tocorrespond with the beveled portions of the Figs. 2 to 16 neck a, thusforming a lead packing upon the part cl, so that when screwed down,until the packing comes in contact with its seat, the cover can stillbeturned down farther to tighten the same without carrying the packingaround with it, which grinds and injures the packing, as in the use ofthe ordinary packing and arrangement of the same. d is provided with Ian extension at the top, 6, having a screwthread on the inside andoutside thereof. On the outside of ia nut, h, is placed, and is screwedinto 2'. These parts form a stuffingbox for the rod f, which is used tobreak the bottle by forcing the same down thereon. f passes through 9 hi and the upper part of (I, as seen in Fig. 1, and is provided at thelower end with a nut after it has been inserted. e

is a guard, permanently secured at the top to the inside of thereceptacle, and open at the bottom; it extends a little lower down thanthe point k, and its object is to prevent the bottle-holder and bottlefrom tipping.

lthas been customary to provide this class of extinguishers with anopening and stopcock near the bottom, through which to discharge theircontents. This construction is liable to the objection that thestop-cock, by

the action of the chemicals thereon, may become corroded, so that itcannot be readily turned. I obviate this difficulty by discharging thecontents, at or near the top of the re ceptacle, through the tube r,placed within the receptacle and extending nearly to the bottom thereof.This tube r, as represented, passes through the top of the receptacle ats. t is a pieceof hose, connected to the tube 0". A stop-cock might beplaced in the tube r just outside of the receptacle, if desired.

The construction described enables me to place the small glass bottle,in which the acid is kept, into the bottle-holder, where it will beready for use, instead of turning the acid into a lead bottle, as hasbeen the usual custom.

The bottle-holder 0 being connected with the cover I), as described,when this cover is removed the bottle-holder can be removed also, andwithdrawn from the receptacle; then, by turning over the cover and part01, which is pivoted to c, as described, a suitable bottle containingthe acid can be inserted into the bottle-holder 0, when thebottle-holder and the bottle therein contained can be inserted in thereceptacle. In screwing the cover to place the bottle-holder 0, rod f,and stuffing-boxes will all rotate with the cover until the lead packing02. comes in contact with the top of the neck a; then the cover properonly will rotate, the other parts remaining stationary. The position ofthe part at, when it is turned over so as to permit the insertion of thebottle into the holder, is represented by the dotted lines in Fig. 6. Inthis figure the part (1 is represented as disconnected from the cover,stuffing-boxes, and rod f, though in use these parts are all together.

p In all respects not herein mentioned the operation of the extinguisheris substantially the same as that of those now in use. The

receptacle A is to be filled with an alkaline and alkali the contents ofthe extinguisher will be forced out through r.

What I claim as new is as follows: ing n, corresponding in form to theneck'a of 1. The bottle-holder c, pivoted to the part receptacle A,constructed and arranged subd, in combination with the receptacle A,substantially as and for purpose specified.
